SPECIFICATION forming part of Letters Patent No. 441,150, datedNovember. 25, 1890.

Application filed May 6, 1890. Serial No. 350,829. (No model.)

To all whom t may concern:

` Be it known that I, ROBERT P. GARsED, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented new and useful Improvements in ElevatorSignaling Apparatus, of which the following is a specification,reference being had to the accompanying drawings to more fully set forththe improvements.

The object of my invention is to provide a simple means of attaching asignal-actuating lever or other operative device to the Wire cage of anelevatorshaft,-as well as providing means for holding in place theVconductors leading to annunciators connected with elevator-cars workingwithin such shafts, my improvements being applicable as well forelectricity or air as the actuating-motor.

The invention relates as well to means of retaining firmly in place thecut ends of wires in the edges of openings in t-he cage in which theact-uatingflevers are placed.

' Figurel representsafront elevatiompartly sectional, showing floor planand general apparatus of an elevator with annunciator in place. Fig. 2is a front elevation of an actuating-lever air-pump in place on a partof elevator-cage. Fig. 3 is a side view of the same. Fig. et shows afront elevation of an air-pump with push-lever for its operation. Fig. 5is a side view of the same. Fig. 6 is a transverse section of a cable orconductor supporting cleat. Fig. 7 is a perspective view of the same.Fig. S is a perspective view of a textile hose inclosing annunciator-conductors and held in place by an ordinary pipe strap or clamp. Fig. 9is a front elevation of part of cage with pump removed, showing the endsof overlapping cut wires. Fig. 10 shows a part of asquare mesh wire cagewith the place of the back part of the push-lever or operating deviceillustrated by dotted lines. Fig. 11 is a detached perspective view ofstrap or clamp and casing, tube, or hose with split end for holding itto Athe wall of elevatorshaft. Fig. 12 is a modified form of Fig. 11.Fig. 13 is a preferred form of conductor-supporting brackets, and iswell suited for sh0rtdistance conductors. Fig. 14 is a side elevationof'actuating-lever, applicable to an electrical system of operation.

Fig. 15 is afront elevation of a supporting-rack for long-distanceconductors.

A, Fig. 1,represents an elevato?.

B is the wall of the elevator-shaft.

C represents any floor of a building to which by the usual process anelevator is made to go.

D are the actuating-levers or pumps placed in a suitable position oneach floor, and serve as an element in operating the annunciator Ewithin the elevator.

F is a cable, and is preferably an ordinary hose of suitable sizeinclosing the conductors G, said conductors at first being bunched t0-gether at their ends and so held while being put within the hose by oneenld of a twine used in drawing them through such hose to a lengthrequired to allow the elevator to ascend and descend.

H is a conductor-supporting cleat, and when in place on the wall of anelevator-shaft should be slanting to overcome the liability of theconductors G closing and preventing-the passage of air, which they areapt to do when of considerable length, and consequently l weighty.

D is an inner clamping-plate with central part cut out, as shown inFigs. 9 and lO, and n serves to hold,with the screws shown in Figs. 2and 4, the actuating-lever plate in place, as well as to keep the partsof the wire cage firmly in position.

I is an ordinary clamp or strap, and serves when in place to keep thecut end of hose F open, as well as securing it in place when used inholding the conductors G.

J is a flanged and flared con ductor-supporting bracket, and when placedin the shaft of an elevator is supported by screws through holes in theflange shown. This device is mostly used with its flange turned facingthe side.

K is a flexible inflatable body having its outlet-tube L at its topcenter.

The operation of the device pneumatically.

is as follows: The actuating-lever D being operated upon any door, theflexible body K is compressed and air is forced through the pipe leadingfrom that oor to the annunciator within the elevator, and by any of theWellknown ways the attention of a proper person is called to the floorfrom whence the call has come.

ICO

To operate by electricity, the movement ot the actuating-lever D, shownin Fig. 14, it will be seen, will produce the same result through anyelectric system-for instance, that of A. I-Iahl, No. 148,447, March 10,1874, electric indicators for elevators.

I do not claim novelty in many of the parts herein shown, as in mypatents, No. 242,297, May 3l, 1881, and No. 264,273, September 12, 1882,I show a clamp supporting a barrel or pipe, and in my patents No.268,882, December 12,1882, and No. 299,636, June 3, 1884, I show aiieXible tube joined to a metal tube; and so with textile casing as anoutside flexible support for conductors or air-pipes, the same has beenused for many years to my knowledge, and also the rubber tubing withtextile covering, as mentioned in patent to Mayall, November 29, 1859,No. 26,276, has for m'any years been used, it being understood that withelevator-annunciators metal pipe or electric conductors are generallyused in a fixed position from the floors to a center point in height ofshaft, and from thence flexible tubing or conductors are used in a looseand suspended position of sufficient length t0 rise and fall with theelevator, and the practice has always been to incase this tubing orthese conductors that are used in this suspended position innon-stretching hose, that the strain incident to their weight may fallupon such hose, Which is preferably textile, as, for a single instance,in the building of Messrs. Strawbridge & Clothier, Philadelphia, where Ihave the improvement here set forth. They have had since 1879 textilehose covering the conductors leading to annuncators in their elevators.

Where there are many floors and great length of tubing is required, itis best not to' bunch such tubing, as the upper layers pressing upon thelower ones by the weight of the suspended-part, such lower layers areapt eral flared projections each supporting a conductor. Heretoforethere has been more or less trouble in fastening actuating-levers to thecages of elevators, wire ties being used as a general thing to supportthem on the outside of such cages. The advantages of my device will beapparent, also, in that it keeps the cut ends of wire in place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isl v 1. The combination, in a signalingapparatu's, of the actuating-lever D,having a front plate andsupporting-screw, and a rear plate D', suitably shaped to receive theparts of such actuating-lever and allow of their movement, a meshed wirecageinterposed between such lever-plates, a conductor G, attached to andleading from such lever, and a flanged and flared supporting-bracket forthe conductors G, and an annunciator adapted to be operated by themovement of said lever, substantially as and for the purposes set forth.

2. The combination, in an elevator signaling apparatus, of an elevatorA, having an annunciator E attached to it, a series of tleXibleconductors leading from such annunciator to the fasteningpoint upon thewall of the shaft of such elevator, and from thence in a suitable Way toactuating devices upon the floors C, a supporting-bracket J, having aange with holes for attachment thereon and a iared and channeled part orparts for
